Respiration

Define Aerobic Respiration

Aerobic respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water. It occurs in the mitochondria and is essential for producing ATP in the presence of oxygen.

define Dehydrogenation

Dehydrogenation is the process of removing hydrogen atoms from a molecule, often involved in metabolic pathways like cellular respiration.

Decarboxylation

Decarboxylation is the process of removing a carboxyl group from a molecule, releasing carbon dioxide. It is a key step in metabolic pathways such as the Krebs cycle.

Oxidative phosphorylation

Oxidative phosphorylation is the metabolic pathway in which cells produce ATP through the transfer of electrons from NADH and FADH2 to oxygen via the electron transport chain, coupled with the phosphorylation of ADP to ATP. This process occurs in the inner mitochondrial membrane and is crucial for energy production in aerobic organisms.

substrate level phosphorylation

Substrate-level phosphorylation is a metabolic process that generates ATP by transferring a phosphate group from a high-energy substrate directly to ADP, independent of the electron transport chain. This occurs during glycolysis and the Krebs cycle.

Where does Glycolysis occur

Glycolysis occurs in the cytoplasm of the cell, where glucose is broken down into pyruvate, producing a small amount of ATP and NADH.

What happens in Glycolysis

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a net gain of 2 ATP molecules and 2 NADH in the cytoplasm. It involves a series of enzymatic reactions that break down glucose in a stepwise manner.

Where does the Link Reaction take place

The Link Reaction takes place in the mitochondria of the cell, where pyruvate is converted into acetyl-CoA, producing NADH and releasing carbon dioxide.

what happens at the link reaction

The Link Reaction is a process in cellular respiration that converts pyruvate into acetyl-CoA in the mitochondria. This reaction produces NADH and releases carbon dioxide, linking glycolysis to the Krebs cycle.
